- Density: red eungella satinash is 785kg/m3 and white eungella satinash is 755kg/m3 at 12% moisture content; about 1.3m3 of seasoned sawn timber per tonne.
- Strength groups: red—(S4) unseasoned, (SD5) seasoned; white—S4 unseasoned, SD5 seasoned.
- Stress grades: F7, F8, F11, F14 (unseasoned); F8, F11, F14, F17 (seasoned) when visually stress graded according to AS 2082—2000: Timber—Hardwood—Visually stress-graded for structural purposes.

- Shrinkage to 12% MC: not available.
- Unit shrinkage: not available.
- Durability above-ground: Class 3 (life expectancy 7—15 years).
- Durability in-ground: Class 3 (life expectancy 5—15 years).
- Lyctine susceptibility: untreated sapwood susceptible to lyctid borer attack.
- Termite resistance: not resistant.
- Preservation: sapwood readily impregnates with preservative.
- Seasoning: slow to dry, be careful seasoning to avoid checking.
- Hardness: moderately hard (rated 3 on a 6-class scale) to indent and work with hand tools.
- Machining: hard to work.
- Fixing: no difficulties using standard fittings and fastenings.

- Texture: fine to medium and uniform; grain slightly interlocked.
- Vessels: small to medium, very numerous, but more so in WES; solitary and short radial multiples; vessels lines not obvious; both often show whitish vessel deposits.
- Parenchyma (soft tissue): difficulty to see under lens.
- Rays: barely visible to the naked eye, and tends towards 2 distinct widths.
- Burning splinter test: match-size splinter from both timbers will burn with some crackling to leave a charcoal tip and black non-adherent ash.
